4)24:6= 4 часа
За четыре часа

Answer 3

Problem Analysis

We are given that the distance between two cities is 24 km. The first pedestrian can cover this distance in 6 hours, while the second pedestrian can cover it in 12 hours. We need to determine how many hours it will take for the two pedestrians to meet.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the two pedestrians is the sum of their individual speeds. We can calculate the relative speed using the formula:

Relative Speed = Total Distance / Total Time

Let's calculate the relative speed:

Relative Speed = 24 km / (6 hours + 12 hours)

Relative Speed = 24 km / 18 hours

Relative Speed = 4/3 km/h

Now, we can calculate the time it will take for the two pedestrians to meet by dividing the distance between them by the relative speed:

Time = Distance / Relative Speed

Time = 24 km / (4/3 km/h)

Time = 24 km * (3/4) h/km

Time = 18 hours

Therefore, it will take the two pedestrians 18 hours to meet.

Answer

The two pedestrians will meet after 18 hours.
